Replacement battery for Acer Aspire

This lithium-ion battery operates at 11.25V and stores 50.29Wh of energy. It replaces part numbers AP18C8K and 3INP5/82/70 across a wide range of Aspire 5, Chromebook 314 and Spin 3 systems. The black pack fits the listed models without modification.

Steady discharge under daily workloads

The 4471mAh cell delivers consistent voltage during extended browsing, document editing or video playback sessions. Capacity remains stable across repeated charge cycles rather than dropping sharply after a few heavy drains. Thermal behaviour stays within normal limits for slim laptop chassis designs.

Rigid housing with factory-aligned connector

The moulded casing resists flex when inserted into the battery bay and the connector pins match the motherboard header exactly. No adhesive strips or shims are required for a secure fit. Buyers needing a higher-capacity pack or a different voltage will not be served by this unit.

Questions about this item

Does the AP18C8K battery generate noticeable heat or noise during all-day use?

Lithium-ion batteries like this 11.25V 50.29Wh unit have no moving parts, so they run silently and produce only minimal warmth under normal load.

What must I already own to install this AP18C8K replacement battery?

You need a compatible Acer laptop from the listed Aspire 5, Spin 3 or Chromebook models and a basic screwdriver set to open the chassis.

Will this 4471mAh battery work properly in an older Aspire 5 A514-53 that originally used a lower-capacity pack?

Yes, the AP18C8K replaces part numbers AP18C8K and 3INP5/82/70, so it fits the A514-53-36J7 and delivers the rated 50.29Wh without issues.
